Greatest Common Divisior

We found the divisors of 82, 15, 12 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 82, 15, 12 is 1.

Therefore, GCD of numbers 82, 15, 12 is 1

Given Input Data is 82, 15, 12

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 82 is 2 x 41

Prime Factorization of 15 is 3 x 5

Prime Factorization of 12 is 2 x 2 x 3

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(82, 15) = 1230

GCD(82, 15) = ( 82 x 15 ) / 1230

GCD(82, 15) = 1230 / 1230

GCD(82, 15) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 12

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 12) = 12

GCD(1, 12) = ( 1 x 12 ) / 12

GCD(1, 12) = 12 / 12

GCD(1, 12) = 1

GCD of 82, 15, 12 is 1
